Question 2

Which of the following is a primary function of the sudoriferous glands?

Answer

Clay and mud masks are highly effective for oily and acne-prone skin because of their absorbent properties. They help draw out excess oil, dirt, and impurities from the pores, leading to a more mattified and refined complexion.

Question 5

Ultraviolet (UV) radiation is a known factor in skin aging and skin cancer. What is the primary characteristic of UVA rays?

Accepted Answer

They penetrate deeper into the dermis and are primarily responsible for premature aging.

UVA rays have a longer wavelength that allows them to penetrate deeper into the skin's dermal layer, damaging collagen and elastin and leading to wrinkles and photoaging. UVB rays are the primary cause of sunburn, while Vitamin D synthesis is also stimulated by UVB.
